[Linux-ia64] __ia64_syscall ?

[Linux-ia64] __ia64_syscall ?

[Martin Wilck]

Hi,

this is probably a stupid question, but I'd spend ours
trying to solve it myself:

The reiserfs Tools 3.x.0j package from namesys.com
defines a Reiser-specific system call with sycall2_().

Linking of the package's programs fails because the
symbol __ia64_syscall is undefined. Examination
of glibc shows that __ia64_syscall is indeed not a global symbol.

This is on RedHat 7.1 (Seawolf).

How do I link such a program?

Martin

Hi Martin

__ia64_syscall is obsolete. The reiserfs-tools package should use the
syscall() interface instead. What they doing is also wrong on the ia32
though it happens to work.

That said please be aware that I do not think reiserfs has been ported
to 64 bit architectures yet. That and the number of severe problem
reports that keeps coming in about it, I'd strongly recommend you stay
far away from it and try a better file system. If you want a journaled
file system, I recommend you take a look at XFS or EXT3. I know that
Martin Petersen got XFS going on the Alpha so it should work fine on
the ia64 as well.

You don't ;-(

Hmm, it works just fine here.  All necessary patches should be included in
2.4.7 already.

Thanks for the quick response.

ReiserFS works on SuSE/IA64. Andreas Schwab told me so (I wouldn't believe
it either), I tried it here (not extensively, though) and so far I have
had no problems. It appears that ReiserFS "simply" needs a few additional patches
the SuSE kernels include.

I am currently trying to find out what these patches are.

It seems that SGI is now providing XFS patches against recent kernels.
Might be worth a try now ... so far I've refused to use their CVS kernel
tree.

Thanks again,
Martin

Ok, I know big endian support is pending, or did Alan submit that
already?

Still doesn't address the issues of it over-writing data beyond it's
partitions, crashing under heavy loads etc.

Hmmm I still wouldn't trust it for any of my data, I have heard of
several incidents where people suddenly start seeing crashes and other
partitions gets corrupted.

XFS would certainly be my choice for anything larger than a couple of
gigabytes.

It does, except that it is a snapshot of XFS as of 2.4.5.  Without a
recent IA64 kernel, that is all we can do.
